If "${index}" is not evaluating, then this is not a Struts problem.
It's an issue with the container you're using and your configuration of
it.For instance, you appear to say you're using Struts-EL. Do you have the correct taglib directives to use Struts-EL as opposed to Struts? What container are you using? > -----Original Message----- > From: Victor Grazi [mailto:[EMAIL PROTECTED] > > We are trying to use <logic:iterate> in a JSP to access items > in a list stored in the Form Bean by the Action class but we > can't seem to get the syntax right. > > I am getting an error meessage from PropertyUtils that > displays the index as '${index}', which indicates that that > struts el expression is not resolving to an int. > > Here is my exact syntax.
